Comment 1 for bug 2009073

Thanks, Stephanie! These are good improvements. Signoff at user/sandbergja/lp2009073-signoff

A note that I tried this with VoiceOver, NVDA, and Narrator, and only one of them (NVDA) announced the highlighting. It's still an improvement for NVDA for sure, and semantic markup is always a plus, but we might want to consider adding some visually hidden text announcing the beginning and end of the highlight as a future enhancement for other screen readers.

I tried this with Windows high contrast mode as well; it was readable using each of the Windows contrast themes.
